Module memtable 

In-memory write buffer (memtable)

Stores mutations in memory using a BTreeMap for partition and clustering ordering. Flushes to L0 SSTable when size threshold is reached.

The memtable maintains mutations in token-sorted order (via DecoratedKey) and tracks approximate memory usage to trigger flushes at a configurable threshold.
